Can someone please make this happen?

There are a million sweet iPhone apps; and I probably own 90% of them. They’re packed with extremely useful features that I’ve become extremely accustomed to.

It’s gotten to the point that when I open the Tumblr app, I expect to see those same features. But then become instantly disappointed, because they aren’t present in any Tumblr apps. I don’t know if it’s because the API doesn’t allow it, or simply that the really talented app devs just aren’t interested, but I wish that’d happen.

What am I really missing? There are overall Tumblr improvements I’d like to see, which would then, hopefully transfer over to any apps that are developed and/or updated.
